It is an object of this invention to provide tion 3 which engages a corresponding recess a locking device consisting of a cross member 7 in the portion 2. In the portion 3 a threadhaving the extremities of a loop mounted on ed opening 8 is provided concentric with the its ends; one extremity of the loop being persleeve 5, and 9 indicates a bolt which extends 5 manently secured to one end or" said cross from a chamber 11 in the outer end of the pormember and the other extremity 1f the loop @031 2 through the said sleeve 5 and engages being provided with a lock to engage portions the threaded opening 8. The head 10 of the within the other end of the cross member and bolt 9 is provided with an annular recess 12 hold it securely thereto. Moreover the loop 1 i purpose hereinafter set forth.

member piece, aloop censisting of tion is susceptible to such alterations and inodifications as fall 'w1thin :the scope of the appended claims.

What I claim is 1.- In a locking device, the combination of a cross member consisting of two pieces in slidable engagement, one of said pieces being tubular for its entire length and having an having its head in said cavity, extending through that pieceof the cross member and in threaded engagement 'with the" other cross tions pivotally connect'echoii-e extremity of said loop being securedto said other cross memberpiecaia lockingmeans on the other extremity of said loop adapted to be held in said-cavit and to en a e the head of said i r? b bolt and hold; it against axial- .movement,

I means, for "preventing, independent rotary movement of said cross member pieces, and opposed projections on said-cross member pieces having transverse grooves formed across theirinner. sides adaptedtog rip the margins of an article to be held.

2. Ina locking de'vice,the combination of a cross member consisting oftwo piecesin slidable engagement, one of said pieces being tubular for its entire "length and having an enlarged cavity atits outer end, a bolt having its head. in said cavity,- extending through that piece of the cross member and being in threaded engagement with the other cross member piece, a loop consisting of two por- .tions pivotally connected, one extremity of said loop being secured to said other cross memberupiece, and a locking means on-the other extremity of said loop adapted to be held in said cavity and engage the head of said bolt to prevent its axial movement.

3. In a locking device, the combination of a two-piece cross member, said pieces being having its head in said cavity, extending through, the tubular piece of said cross-memnular recess around itfai loop consisting of two por-' in said bolt head, and said locking means being adapted to enter said cavity.

d. In a locking device of the character described, the combination of aimembe r tubular .for its entire length'and having an enlarged cavity, a latch rotatable on said plug adapted to engage said-fastening member and hold the latter a ain'st' axial movement and o Osed j 131O]BCll1Q11S on theouter ends or saidmembers havin 'o soosed roovesformed in their inner 5. ln a locking device of the character described, the combination of a member tubular for its entire length and having anenlarged cavity at one end into which the tubular portion opens a second member tubular at one. end, the tubular portion beingslidable in said first named member and, being internally threaded, means holding the two members againstindependent rotation,- a bolt the head of which rests in said cavity, said bolt extend-- ing through first named member and being in threaded engagement with the iii-- ternally threaded portion of the second mem-- her, an annular groove formed around said bolt head, aplug in saidcavi'ty, a latch -rotat able in said plug adapted to engage said an nular groove to hold the bolt against axial 'movement, and projecting portions on said their inner sides between which an object is ber and being in'threaded engagement withv the other piece, said bolt head havingan antwo pivotally connected portions, one portion being secured t0 the other piece of said cross membena locking means, on the other extremity of said loop, a latch said locking means adapted to engage the annular recess
